ToaZZ whom it mag concern:

' Be 1t known that I, JOHN J. PETERSON, a citizen of the United States, residing at Steubenville, in the county of Jefferson and State of Ohio, have invented new and useful Improvements in lVindow-Cleaning Devices.

of which the following is a specification.

This invention relates to cleaning devices and more particularly to a device specially adapted for cleaning windows and for similar purposes,

One of the main objects of. the invention is to provide a power driven device of 81111 ple construction and operation by means of which windows may be quickly and easily A further object is to provide a device by means of which the window may be effectively washed and dried by a single operation.- A further object is to provide a device having a removable head and driving means therefor so constructed that, when the head is inoperative position, it is con nected to the driving means so asto be operated therefrom Further objects will appear from the detaileddescription.

In the drawings Figure 1 is a back view of a cleaning device constructed in accordance with my invention, partly in section. 4

Fig.2 is an end view of the head with'the gear cover removed.

posite end to Fig. 2.

Fig. 4 isa side view.

Fig. 5 is a section taken substantially on line 5-5 of Fig. 1.

Fig. 6 is a detail plan view of the wash-' in g solution container and drip receiving an. p In constructing the cleaner I provide a substantial rectangular or box like casing designated generally by 1. A brush 2 is rotatably mounted in this casing longitudina-lly thereof and projects beyond theopen front of the casing. This brush is positioned below a drying and polishing roller 3 of rubber or other suitable material which is rotatably supported at the rear of the casing and presses against roller 3 so as to remove moisture therefrom. A sheet metal scraper 5 is pivotally supported at its upper end on a rod 6 and is held in engagement with the roller 4. by leaf springs 7 secured to back position. 'tegral drip pan 19 the top of which is open,

Fig. 3 is a similar view taken from. the opwall 8 of easing 1. A similar scraper 8 is held against roller 3 by. wire springs 10.

mounted on the inner faces of the ends 11 of clined downwardly and rearwardly of the casing and is supported at'each end by 'sub# i stantially U-shaped members 13 projecting inwardly from the ends 11. This deflector serves to receive the moisture removed from roller 3 by -scraper 9 and to direct this .moisture onto the downwardly and. rearwardl y inclined top wall 14: of a sheet metal container or tank 15 which extends longitudinally of the casing 1 adjacent 'the brush 2. This tank isslidable through an open ing provided in one end of the casing and has the forward portion of its bottom wall extended to provide a flange 16 which engages beneath an angular guide strip 17 se cured to the bottom of the casing. A guide strip 18 is secured to back wallS'and cooperates with strip 17 to holdthe tank in The tank is formed with an inwhich is positioned to receive the moisture removed from the pressure roller 4 by scraper 5. In this manner, the drying andpolishing roller 3 is kept free from moisture and this moisture is collected within the pan .19.

The tank 15 is provided with an opening through its top wall 14 which is normally closed by a plug or stopper 20 so as to permit a suitable washing solution to be poured into the tank. The tank is further provided with an opening through its front wall which communicates with a wick tube 21 in which operates a wick 22 of suitable type, this wick being submerged in the solution in the tank and projecting so as. to rest against the bristles of the brush 2 and feed the solution thereto by capillarity. The wick is operated in tube 21 by means ofa rod 23 and star wheels 24 secured thereon and I projecting through slots in the top wall of the tube in the known manner; This rod projects beyond one end of easing 1 and'is provided with a finger wheel or grip 25 secured-thereon to permit the wick to be adjusted to suit circumstances.

The shaft ofroller 3 is reduced at each end and projects through the end 11 of the casing to receive a spur gear '26 secured thereon. This gear meshes with a pinion 27 secured on a stub shaft 28 projecting from ice-l1 the 'end of-the casing, which pinion meshes with a gear 29-secured on the'end of the shaft of roller 14, this shaft being also re duced at each end and extended through the ends 11 of the casing for receiving the gears.

The reduced end portion-30 of the shaft 21 I of roller 4 is mounted in a block 32 slidable inopening 33' through'end wall 11 of the casing, this opening being concentric with therein by pressure screw 38 threaded through the upper portion of end wall 11. By means of the pressure screws 38 and the parts associated therewith, the roller 4 may be held in tight contact with roller 3 so as to be forced against the same with any desired degree of pressure.

At each end of the casing, I provide a gear housing 39 which is adapted to fit overv the gearing so as to-e'ffectually protect the same. One of the gear housings carries an inwardly projecting stub shaft 40 upon which is rotatably mounted a spur :gear 41 which meshes witlra drive pinion 42 secured upon the outer end of a shaft 43 rotatably mounted in bracket 44 secured to the back wall 8 of casing 1. At its inner end. shaft 43 is provided with a bevel gear 44 secured thereon which meshes with a bevel gear 45 rotatably supported by bracket 46 secured to the back of the casing. Bevel gear 45 is connected by a flexible shaft 47 to a spur gear 48 rotatably supported by a bracket 49 secured to yoke 50 for supporting the casing 1. This yoke is formed of two arcuate elements 51 which are )ivotally secured at their upper ends to the gear housings or casings 39, at 52, and are secured together at their lower ends to form a downwardly tapering member 53 which fits snugly into a corresponding socket 54 formed in the upper end of a flattened element .55 of a tubular, handle .56 which is preferably, though not necessarily, of sectional construction. The member 53 is releasably secured in socket 54 by a binding screw 57 or in any other suitable manner. When the yoke 50 is thus at tac-hed to handle 56, gear 48"meshes with a. drive gear '58 secured on the armature shaft 59 of an electric motor 60 of suitable type which is secured to the. flattened member 55,

a cord 61 being passed through the tubular handle 56 by means of which the motor may be readily connected to a suitable source of supply of electrical energy. By this means,

when the head of the cleaning device, composed of the casing l and associated parts and the yoke 50, is securedto handle 56,

64 which projects from theouter face of a spur gear 65 rotatably mounted on a stub shaft 66 projecting from end 11- of the easing. Gear .65 meshes with a pinion 67 secured upon one end of the-shaft 68 of brush I 2, the shaft of the brush being reduced at one end and extending through'the end of the casing for this purpose.

A spacing roller 69 is, provided at each end of the casing 1,this roller being mounted upon the forward end of an arm 7 0 which is slidably mounted transversely of the casing, this arm being provided with a longitudinally extending slot' 71 which receives a pin 72 secured in the end of the casing and a screw 73 spaced relative to the pin and adapted to receive a binding nut 74 by means of which the arm, may be secured in longitudinal adjustment. These rollers may be adjusted toward or away from the front of the casing and are adapted to engage the glass ofthe window for holding the casing in proper spaced relation thereto at its lower edge. f

As will benoted more clearly from Fig. 4, the arms 51 of yoke 50. are arched rearwardly so as to-provide clearance when washing windows having relativelybroad or deep sills or frames.

lVhen using the washing and cleaning device, the head is moved downwardly over the window glass, the brush Qand roller 3 being rotated. During this movement of the head, brush 2 serves to effectually moisten and wash the surface of the glass. roller 3 serving to remove the moisture from the glass surface so as to dry and polish the same. The moisture which adheres to roller 3, together with particles of dust and. other foreign material, is scraped from the roller 'by means of the scraper 9 and deposited upon the deflector 12. Roller 4 serves to effectually dry roller 3, and the moisture is removed from roller 4 by scraper 5 from which it flows into the drip receiving pan 19 of shank 15,, the moisture originally removed from roller 4 being directed by deiiector 12 and the inclined top wall 14 of the tank into the drip p'an. By this means, a window maybe quickly and easily cleaned at a minimum of time and expense ,1 p

As'will be noted more clearlyfioni Fig. 5, the deflector 1:2 is bent at its forward portion to provide asupplemental drip, receiving pan 12 positioned between roller 3 and brush 2. This pan is provided with an inwardly directed relative narrow opening to receive drippings from the. deflector. The supplemental drip pan is intended to catch mixture drained from the deflector when the device is used under conditions where it is necessary to tilt the casing 1 at a downward and forward inclination, which often occurs in practice. I

hile I have illustrated and described the brush 2 as being of a bristle construction, it will be readily understood that this brush can be of rubber or any other suitable construction preferred. Also, it may be found advisable in practice to resort to slight variations in details of construction and arrangement of the different parts of the invention. and I intend to include all such va.- riations, as fall within the scope of the appended claims, in' this appli *ation in which a preferred form only of my invention is disclosed.
